SY89295UMG-TR

Overview

The SY89295UMG-TR is a programmable delay line from the Precision Edge series by Microchip Technology. It provides a delay range of 3.2ns to 14.8ns in 10ps increments using a 10-bit control word, with an additional bit for cascading. The device operates on a 2.5V ±5% or 3.3V ±10% supply and supports LVPECL inputs/outputs. It guarantees AC performance up to 1.5GHz with less than 160ps rise/fall times. Jitter specifications include <10ps peak-to-peak total jitter and <2ps RMS cycle-to-cycle jitter. It functions within an industrial temperature range of –40°C to +85°C.

Procurement Notes

Verify the component origin as Micrel, now part of Microchip Technology, when sourcing the SY89295UMG-TR. Confirm that the specific ordering suffix corresponds to the MLF-32 package type and lead finish requirements. Ensure compliance with RoHS3 specifications if applicable to the project constraints. Cross-reference datasheet M9999-032511 for accurate electrical parameters before finalizing procurement decisions.

Selection Notes

Select the SY89295UMG-TR for applications requiring precise digital delay control with LVPECL interfaces. Consider the 10-bit resolution for fine-tuning timing requirements. Evaluate the need for cascading capabilities if delays exceeding 14.8ns are necessary. Ensure the system power supply aligns with the 2.5V or 3.3V operating ranges specified in the datasheet.

Part Context

The SY89295U belongs to Micrel’s high-speed Precision Edge product line. It is designed for high-frequency signal processing where precise timing alignment is critical. The device complements other programmable delay lines like the SY89296U, which offers analog fine-tune control. It serves as a key component in systems demanding low jitter and high-speed operation.

Replacement Considerations

The SY89297UMG-TR is documented as an improved dual-channel version of the SY89295U. Verify pin compatibility and functional differences before substitution. Check current availability status as the SY89297UMG-TR may have different stock levels.
